Resumo(s)
De acordo com os dados da União Europeia, o consumo energético em edifícios representa atualmente cerca de 40% do consumo de energia final. Este consumo está diretamente relacionado com o facto destes edifícios serem sobretudo de construção antiga e necessitarem de grandes quantidades de energia por forma a manter temperaturas de conforto dentro do edifício. Estes consumos podem ser diminuídos a partir de uma renovação energética nas suas estruturas construtivas e sistemas técnicos, pelo que a Comissão Europeia obriga os seus Estados-Membros a estudar e a adotar uma estratégia que consiga renovar o parque edificado até 2050. Em Portugal considera-se que existe um potencial de renovação prioritário de 286 km2 de área pavimento no caso dos edifícios residenciais. Este potencial pode ser renovado com recurso aos vários fundos de investimento já existentes, contudo, de forma a cobrir todo o potencial é necessário que o Estado tome medidas adicionais de forma a anular os obstáculos ainda existentes. Estas medidas podem ser legislativas e regulamentares, por exemplo. No caso dos edifícios de comércio e serviços a informação existente ainda é pouco clara e robusta sendo desde já necessário recorrer a novos levantamentos estatísticos de forma a melhorar a visão do parque imobiliário existente.
According to the European Union energy consumption in buildings accounts for nearly 40% of the final energy consumption. This share is highly connected to the fact that the buildings are under-prepared in it's construction, for an extent of reasons. This means that they need a lot of energy delivered to help maintain the temperatures inside [the building] well inside the temperature comfort-zone band. This high-energy demand can be decreased mainly by a set of energetic renovations to their structures and technical systems. The European Union demands that his member-states must study and adopt a strategy accordingly, in order to up to 2050 the buildings stock must be fully renovated. In Portugal there is a target that should be prioritized of 286 sqkm of floor area for the domestic sector. This target can be renewed through investment funds already in place, however, in order to cover all the target, it is necessary for the State to take additional measures in order to overcome the remaining obstacles. These measures may be legislative or regulatory, for example. For the commercial and service buildings the existing information is still unclear and robust, in order to improve the vision of the existing stock it is now necessary to resort to new statistical surveys.
